Problems solved by technology

None of the foregoing references disclosure address the problem of maintaining a uniformly even temperature in a refrigerated cargo space containing refrigerated fruits and / or vegetables.
Uneven temperature can be a problem resulting from a loss or gain of heat through the walls of the cargo hold during shipment.
However, this disclosure does not address the problem of uneven flow of refrigerated air through the pallets in the cargo chamber.
This uneven air flow results in troublesome differences of temperature in various locations of the cargo chamber.

Embodiment Construction

Turning now to a description of the drawings, FIG. 1 shows the elongated tubular airbag 10 of this invention comprising five sections, 12A-E. The bag is made of durable flexible pvc. A baffle 14 separates each section from its neighboring section and each section is provided with a valve 16 so that each section can be inflated independently. To accommodate the typical situation of two rows of nine pallets, each pallet being four feet long, sections 12A-D are each eight feet long, and the last section 12E is four feet long.

The lead section 12A is provided with a pair of flaps 18, each flap having an edge secured to the lead section and arranged opposite one another along the length of the section 12A.

FIG. 2 shows the first step in loading the cargo which is to position the first four pallets each holding a stack of boxes 13, two abreast at the cab end of the cargo space. The lead section 12A is secured in place by taping each flap 18 to the top surface of one stack opposite the other...

Abstract

An apparatus and method for storing boxes of perishable products and providing that refrigerated air flows relatively uniformly through the stack. The apparatus is an elongated inflatable bag divided into sections by baffles, each section being inflatable independent of the other sections. The bag forms a roof over a corridor between two rows of stacks and a panel encloses one end of the corridor opposite the opposite end which is closed off by the cargo wall. Refrigerated air forced into the corridor at floor level at one end of the corridor is diverted through the stacks of boxes.

Description

This invention relates to air bags such as are used to protect products shipped in trucks and particularly to an air bag that distributes refrigerated air flow to obtain a more even temperature.BACKGROUND AND INFORMATION DISCLOSUREIn transporting products in the enclosed cargo space of trucks and containers, inflatable air bags are used to stabilize the load of the cargo to prevent damage to either the truck or cargo. Variations of this practice have appeared in the patent literature.For example U.S. Pat. No. 5,730,564 to Howlett discloses a cargo supporting air bag having inflation indicating means and a method for determining proper inflation of spaced loads.U.S. Pat. No. 5,263,801 to Keenan et al discloses an airbag for use in a cargo bay of a transport vehicle for stabilizing a cargo of drums or rolls.In the transportation of perishable products such as fruits and vegetables, the produce is normally packed onto pallets and which are then placed in the cargo space of a refrigerat...
